So let's rewrite this response
- Not any proof of this cheating thing, btw you can't cheat on an iq test and there are many other test are showing the same gap (SAT, LSAT, ACT).

- False concensus fallacy, Intelligence can be measured the first dimensions (the g factor) account for 40% of the variance.

- Tests aren't biased, I they were biased there wouldn't be strict measurements invariance see :

There is also a study were item judged as the least biased against blacks shows the biggest gap.

Raising your iq is possible via training but this gains aren't on the latent factor (g) see : https://www.sciencedirect.com/science/article/abs/pii/S0160289606000778

These gains would create measurement variance because their effect isn't on the latent factor.

- nice anti-white stuff and misconception about medieval Europe, as an European I find this funny (Have you ever heard of antiquity, The Roman Empire, the Greeks, Charlemagne, the holy Roman Empire, the Byzantine Empire, the Venitians and the entire Renaissance which is the rediscovery of the antique Greco-Roman culture in northern Italy). Btw every single advanced culture at that time recognized 2 gender ex: Arabs, Mongols, Chinese, Persian, etc..

The existence of intersex people (genetic defect btw) doesn't falsify the existence of only 2 genders.

You have no proof POC as you say (more like 50 shades of brown lmao) are not treated fairly see more about it here https://ideasanddata.wordpress.com/2019/08/10/on-racial-bias-in-police-shootings/

- Most terrorist in WEIRD country are Muslims :) As a French I find you somewhat offending.

The only racist thing is what I call the equalitarian syllogism :

The equalitarian syllogism.
P1:Race differs in outcome
P2:Race differences in phenotype that causes these outcomes are environmental
C1:Some race are environmentally privileged
C1:it's right to discriminate against certain race to ensure equal environment and therefore equal outcome
